Lette/rs Patent No. 84,118, dated lo'vefmbefl- 17, 1868; antedatcd November 5, 1868.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, DAVID B. HEBBEN, of Newark, in the county of Essex, and State oi' New Jersey, have invented a new and improved Mode oi Constructing a Chair or Stool; and 4I do hereby declare that the following is a full and exact-description of the same, reference being had'to the accompanying drawings, and to the letters of reference marked thereon.

The principal part of my invention consists in the Vmode of preparing the seat C ;4 first, by means of one or more pins el, running across the grain of and through the seat, for the purpose of giving additional strength to the same. Besides this, holes E are bored into the seat from the edge, for the purpose of reducing the Weight of the seat. The holes are closed at the outer end by plugs F.

It is also contemplated making the wood of the seat air-tight, and then the holes will be filled with compressed air, to give additional lightness tothe seat. They are particularly designed to be used on board of boats, where theirlextra buoyancy will enable them to be 1'used as a float in the place of a life-preserver, should any such need occur. This providesa light and very desirable arrangement of a chair, and at ,the same time adapts it to use as a life-preserver.

My invention consists, further, in the mode of con structing and attaching the legs A B to the seat. They are made of one piece of wood, bent into the desired form. The wood is levelled oii" on the top, and screwed or otherwise secured -to the seat, so vthat the grain of the Wood forming the legs runs crosswise of the seat, to assist in keeping it from splitting.

Another part of the invention is the adjustable back G, attached to the under side of the seat. This is done by means of the metal pieces H, made fast to the outer posts'I of the back, whichA pieces are made to slide into grooves K, secured to the bottom of the seat. The metal pieces may be secured to the posts either with a strip riveted to the side of them, or with sockets, into which the ends of the posts are driven. Other devices may be employed in the place of the grooves K, only so that the principle of adjusting the back to the bottom of the seat is retained.

What 1 claim as my invention, and desire to secure
